Abstract

The present invention discloses a high-temperature superconducting magnetic suspension feature test device. The device comprises a pedestal; a vertical main body; a cantilever vertically and movably arranged on the vertical main body; a sliding platform horizontally and laterally movably arranged on the pedestal, wherein the sliding platform is provided with a permanent magnetic guideway; a low-pressure device comprising a sealing box body and a superconductor arranged in the sealing box body and generating magnetic force with the permanent magnetic guideway together, wherein the sealing box body is arranged on the cantilever; a vertical force sensor configured to detect the force on the vertical direction on the superconductor; and a horizontal force sensor configured to detect the force on the horizontal and lateral direction on the superconductor. The high-temperature superconducting magnetic suspension feature test device changes the position between the superconductor and the permanent magnetic guideway and the air pressure environment around the superconductor to change the test parameters and the environment so as to realize the high-temperature superconducting magnetic suspension system performance test in the low-pressure environment.

Description

technical field [0001] The invention relates to the technical field of high-temperature superconducting magnetic levitation, in particular to a high-temperature superconducting magnetic levitation characteristic testing device. Background technique [0002] In the field of high-temperature superconducting magnetic levitation technology, technicians have proposed the method of evacuating and decompressing to achieve the purpose of liquid nitrogen supercooling; then place the circular high-temperature superconductor in supercooled liquid nitrogen (temperature lower than 77K) for magnetization , the experimental results verified the effectiveness of this method for improving the performance of high-temperature superconductors. Subsequently, many groups at home and abroad used this method of evacuation and decompression to build a nitrogen fixation experimental platform to conduct research on the magnetization of high-temperature superconductor magnets and the application of str...
